| Abstract: | Based on several altered rocks in the Chambishi copper deposit and the spectral characteristics of the rocks existing in VNIR-SWIR bands of ASTER data,the authors adopted the methods of Relative absorption-Band Depth(RBD)and band ratio to enhance the mineral alteration information in this paper.The band ratio of ASTER 2/ASTER 1 and the RBD of ASTER 3 were used to enhance the chalcopyrite and pyrite information,the RBD of ASTER 8 was used to enhance biotite and calcite information,and the RBD of ASTER 6 was ... |
